I think that the idea of storeys is more complicated than it seems when one is dealing with split levels. I've got a job to an existing building with multiple split levels, varying by about 1.4 - 1.7 m. Having decded to use only two main storeys for floors (plus storeys for roof and footings as recommended), I struck a snag with cutting planes. These are related to storeys, not slab levels. Whist it was set correctly for the main level, it missed the walls on a split level and doors in those walls disappeared. I had to adjust the cutting plane to compensate.
Should cutting planes be linked to slab levels, rather than storeys?
